Abstract:
Hearing fast-tempo music in the background is shown to affect the pace of motor
behavior. However, the mechanism underlying this phenomenon remains unclear. We
investigated how tempo influences behavioral pace in a simple perceptual-motor
task in which participants heard background sound sequences (30, 60, 120, 180,
and 240 bpm) while performing a line-tracing task. The order of the tempo
conditions (ascending vs. descending series of tempo) was manipulated. When
sound sequences changed from slower to faster tempi (that is, ascending series),
behavioral pace accelerated. However, the pace did not change in the descending
series. The subjective arousal level increased under faster tempo sounds
regardless of tempo series. The results indicated that the ongoing tempo of
background sounds did not determine the behavioral pace directly through
increased arousal or perceptual-motor synchronization. Not only the ongoing
tempo but also the preceding tempo of background sounds is shown to be an
important factor for behavioral pace change.
